With Myers gone? Unless they gave up their top 3 leftover or someone like Hosmer/Moustakas off their major league roster, they really don't.

The Cardinals and Royals fit well in the fringes (the have bit parts that match up well), but even before Myers left, they weren't a good fit for a major trade. The Cards are strong at the corners with Beltran, Holliday, Freese and Craig, then they have Carpenter, Adams and Taveras in the minors. That's a shitload of quality corner bats and that's where all the Royals legitimate trade value comes from.
